Formula involved in calculating Flexuliar Bending

[ronmarie]

Hi! I'm new.

I was just want to size Cloumn using a steel which carries a sign board area of 16.60 sq. m and a wind velocity of 130 Km/hr. is it possible to caculate the stress using those two (2) given?

Thank you

Yes.

Use the sign's frontal area and the wind speed to calculate the overall force. Once you have that you can assume the load is equally shared between the two beams. Treat them as cantilever beams with the force applied to the very end of the beam. From there it's basic beam theory to calculate the flexural/normal stress, i.e.

$$\sigma = \frac{My}{I}$$

for your question. The formula for calculating flexural bending is: Stress = (M * c) / I, where M is the maximum bending moment, c is the distance from the neutral axis to the outermost fiber, and I is the moment of inertia of the cross-section.

In order to calculate the stress in your specific scenario, you will need to gather additional information such as the dimensions and shape of the steel column. Without this information, it is not possible to accurately calculate the stress using the given parameters of sign board area and wind velocity. Additionally, other factors such as the material properties of the steel and the design of the column will also affect the calculation. I recommend consulting with a structural engineer or using a structural analysis software to accurately determine the stress in your column.
